Subject: [Haskell-beginners] LYAH example
Message-ID: <[email protected]>
Content-Type: text/plain; charset=us-ascii
Hi All,
Can someone clarify the example I got from LYAH book. This let statement is
kinda confusing to me :
applyLog :: (a, String) -> (a -> (b, String)) -> (b, String)
applyLog (x, log) f = let (y, newLog) = f x in (y, log ++ newLog)
I know that f applied to x should produce y and we append log with newLog but
when reading ... f x in (y, ... I just don't see how f x becomes y in the let
statement.
Seems more readable if we could write ... = (f x, log ++ newLog)
Thanks, Sasa
